Keep your body moving with the absolutely fabulous Zon Stability Disc. This ground breaking Health & Fitness Gear from the fine folks at Zon can be used standing, sitting, kneeling, laying down and in tandem with exercise equipment such as balls, resistance tubes or two Stability Discs at a time to perform standing or squatting exercises. By destabilizing the surface up on which you exercise, core stabilizing muscles are more challenged and active as you work to keep your balance, alignment and posture. The ability to know where your body parts are in 3-dimensional space, and to control your motion, is required for every movement we make, and is also the most basic skill needed in practically every sport. Don't move your booty without the Zon Stability Disc.
